Abstract (en)
[origin: US4623416A] The present invention relates to aqueous solutions or dispersions of polyisocyanate polyaddition products containing from about 2 to 200 milliequivalents per 100 g of solids of chemically incorporated, ternary or quaternary ammonium groups and up to about 25%, based on solids, of incorporated ethylene oxide units present within terminally and/or laterally arranged polyether chains, characterized in that the polyisocyanate polyaddition products contain from about 20 to 95% by weight of polyester segments Q incorporated through urethane groups, wherein Q represents a radical of the type obtained by removing the hydroxyl groups from (i) dicarboxylic acid polyester polyols having a molecular weight in the range from about 700 to 1400 and/or (ii) hydroxyl-terminated lactone homopolymers or copolymers having a molecular weight in the range from about 700 to 2500. The present invention also relates to the preparation of these polyisocyanate polyaddition products and their use for bonding substrates, in particular rubber.
